We look at the division of 66102639 by 452 
We're looking to find how many times 452 goes into 66102639.

Moving on to step 1:
The number 452 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 452

Moving on to step 2:
66 divided by 452 is 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Append the next digit (1) from the dividend to 66 and continue with: 661 / 452

On to step 3:
452 can be fit into 661 1 times, resulting in a remainder of 209.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 452 from 661, we get 209.
Fetch the next digit (0) from the dividend, attach it to 209 and continue: 2090 / 452

Step 4:
When dividing 2090 by 452, we get 4 with a remainder of 282.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 282 after subtracting 1808 from 2090.
Include the next digit (2) from the dividend after 282, then repeat: 2822 / 452

Step 5:
452 goes into 2822 6 times with a remainder of 110.
Write down 6 as next digit of the result. 
Result so far: 146.0
Subtract 2712 from 2822 to get 110.
Append the next digit (6) from the dividend to 110 and continue with: 1106 / 452

Let's proceed to step 6:
If we divide 1106 by 452, we get 2 and a remainder of 202.
Write down 2 as next digit of the result. 
Result so far: 1462.0
If we take 904 away from 1106, we end up with 202.
Append the next digit (3) from the dividend to 202 and continue with: 2023 / 452

Step 7:
452 goes into 2023 4 times with a remainder of 215.
Use 4 as the next digit of our solution. 
Result so far: 14624.0
Subtract 1808 from 2023 to get 215.
Bring next digit (9) of the dividend behind the 215 and repeat the process: 2159 / 452

Advancing to step 8:
2159 divided by 452 is 4 with a remainder of 351.
Put 4 as the next digit of the answer. 
Result so far: 146244.0
Deduct 1808 from 2159 and we're left with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Advancing to step 9:
452 can be fit into 3510 7 times, resulting in a remainder of 346.
Put 7 as the next digit of the answer. 
Result so far: 146244.7
Subtract 3164 from 3510 to get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Step 10:
452 can be fit into 3460 7 times, resulting in a remainder of 296.
The number 7 becomes the next digit in our result. 
Result so far: 146244.77
Subtracting 3164 from 3460 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

In conclusion, the division gives 146244.77 with a balance of 0.296.
